目的:针对腹壁注射分子肝素钙的患者,注射后按压时间的长短与皮下出血发生率及出血面积的关系,同时找出适当的按压时间,以减少皮下出血的发生,减少出血面积。方法:选择2010年6月-2011年8月腹壁注射低分子肝素钙的患者50例,将每例患者的16次腹壁注射按局部按压时间的长短分为8组,每组按压时间分别为3、4、5、6、7、8、9、10min。观察皮下出血的发生例次及出血面积的大小。结果:腹壁注射低分子肝素钙后,局部不同按压时间与皮下出血的发生率及出血面积的大小之间存在关联。结论:腹壁注射低分子肝素钙后局部按压7min可以有效降低皮下出血的发生率并缩小出血面积。
OBJECTIVE: To investigate the relationship between the time of injection and the incidence of subcutaneous hemorrhage and the area of hemorrhage after injection of molecular heparin calcium in abdominal wall. At the same time, find out the appropriate pressing time to reduce the occurrence of subcutaneous hemorrhage and reduce the bleeding area. Methods: From June 2010 to August 2011, 50 patients underwent abdominal injection of low molecular weight heparin calcium into the abdominal cavity. Sixteen abdominal injection per patient were divided into 8 groups according to the time of local compression. The compression time of each group was 3 , 4,5,6,7,8,9,10 min. Observe the occurrence of subcutaneous hemorrhage cases and the size of the bleeding area. Results: After the injection of low molecular weight heparin into the abdominal wall, there was a correlation between the different local pressing time and the incidence of subcutaneous hemorrhage and the size of bleeding area. Conclusion: Local injection of low molecular weight heparin calcium in the abdominal wall for 7 minutes can effectively reduce the incidence of subcutaneous hemorrhage and reduce the bleeding area.
